2.8 Operation logic

The diaphragm valve moves downward. The movement of diaphragm valves acts on

Feedback spring through Feedback lever and Flapper increases torque to the left pull. The

diaphragm valve is balanced at the position between the above spring torque and magnetic

field strength generated by the input current. Gain suppression spring is used to immediately

feedback the movement of the Pilot Valve to the Flapper and it increases the loop* stability.

<Logic 5700L Operation >

* The diagrams above explanations based on 5700L linear type and Diaphragm valve of

RA (Reverse Action) type. 5700R rotary type is same as Operation logic of 5700L linear

type except feedback structure.

* Nozzle back pressure internal pressure of Nozzle depends on the control the Nozzle by

the Flapper.

* Loop Positioner and Control valve consist of closed-circuit through Feedback lever.

2.10.2 5700R Dimensions

Operation Logic

When the input current (4-20mA) increases, Armature receives counter-clockwise rotating torque as a

magnetic field strength of Torque motor and Flapper moves to left as the center of Plate Spring. When

the space between Flapper and Nozzle opens, the Nozzle back pressure* decreases. As a result,

Exhaust valve of Pilot valve moves to right. At the same time, Supply valve A of OUT1 moves to right

and opens Supply valve. Air supply through OUT1 increases air pressure of diaphragm and

6 Adjustment

CAUTION

Zero and span must be set correctly so product can be operated normally. If the setting is

not correct, impact on performance like linearity and so on. Please the zero and span

position must be set correctly.

6.1 Zero and Span Adjustment

① Set the input current to 4mA and turn the zero adjusting knob by hand to set it to the

actuator starting 0% point.

② Then, set the input current to 20mA DC and check the actuator stroke. At this point,

depending on whether the span is too large or too small loosen the lock screw and then

adjust the span as shown in the illustration above, set it to the actuator 100% end point.

③ It shall set the input current to 0% and conduct the zero point adjustment, as done is

step1 again, because Span and zero point adjustment interfere in each other.

④ Repeat the above operations until the predetermined stroke of the actuator is obtained to

the input current.

6.2 Setting of the Position transmitter (Option)

For the general case, set 2 point that belongs to from 0% position to 100% position of the

Valve. For more precise feedback, set 5 point.

2 points setting

① Input the current signal 4mA to make the

valve stroke on 0% an than press the button

with 4mA on the left for 2seconds, which can

lead the setting lamp to turn on gradually and

rapidly while the location in formation is saved

automatically.

② Input the current signal 20mA to make the

valve place on 100% and then press the

button with 20mA on the right for 2 seconds,

which can lead the setting lamp to turn on

gradually and rapidly while the location

information is saved automatically.

5 points setting

① First, input the current signal 4mA to make the valve stroke on 0% and then press the buttons with

4mA as well as 20mA for 2 seconds at the same time, which can lead the Number 4 setting lamp

to blink.

② Pressing the button with 4mA just once makes that the valve is set to output 4mA value from 0% a

nd moves to Number 8 lamp automatically and blinks.

③ Input the current signal 8mA to make the valve place on 25% and then press the button with 4mA j

ust once, which can lead the valve to be set to output 8mA on the right position.

④ In the same way, set them in order to output 12mA, 16mA and 20mA according to each position of

the valve 50%, 75% and 100%.

⑤ When 100% setting-up is completed, all the setting lamps get turned off.

How to change DA/RA

This is the direction in which the feedback signal is changed.

When 4mA is inputted, get 20mA feedback. When 20mA is inputted, get 4mA feedback.

① Input the current signal 4mA to make the valve stroke on 0% and then press the button with 20mA

for 2 seconds, which can lead the setting lamp to turn on gradually and rapidly while the location

information is saved automatically.

② Input the current signal 20mA to make the valve stroke on 100% and then press the button with 4

7.3 Position transmitter

Phenomenon Feedback signal dead zone

Cause Potential meter gear breaks away by a strong shock or vibrate.

Explanation The paint mark position of the upper part of the main shaft gear and the paint mark position of the upper part of the potential meter gear must coincide to become a normal state.

(Picture1) Normal condition (Picture2) Gear breaks away

How to adjust when the gear breaks away

① Open the cover of the product. Unlock and take out one of 2 M3 fixing bolts for Potential

meter. Unlock the other bolt just a little and then pull it down slightly, which can lead the p

otential meter gear to break away from the main shaft gear.

② When the carved positions are engaged each other, adjust the potential meter gear to put

them on a straight line.

③ When the adjustment is completed, fix the potential meter with M3 bolt.
